Resource: awsWafSizeConstraintSet

Provides a WAF Size Constraint Set Resource

Example Usage

/*Provider bindings are generated by running cdktf get.
See https://cdk.tf/provider-generation for more details.*/
import * as aws from "./.gen/providers/aws";
new aws.wafSizeConstraintSet.WafSizeConstraintSet(this, "size_constraint_set", {
  name: "tfsize_constraints",
  sizeConstraints: [
    {
      comparisonOperator: "EQ",
      fieldToMatch: {
        type: "BODY",
      },
      size: "4096",
      textTransformation: "NONE",
    },
  ],
});

Argument Reference

The following arguments are supported:

  • name - (Required) The name or description of the Size Constraint Set.
  • sizeConstraints - (Optional) Specifies the parts of web requests that you want to inspect the size of.

Nested Blocks

sizeConstraints

Arguments

  • fieldToMatch - (Required) Specifies where in a web request to look for the size constraint.
  • comparisonOperator - (Required) The type of comparison you want to perform. e.g., eq, ne, lt, gt. See docs for all supported values.
  • size - (Required) The size in bytes that you want to compare against the size of the specified fieldToMatch. Valid values are between 0 - 21474836480 bytes (0 - 20 GB).
  • textTransformation - (Required) Text transformations used to eliminate unusual formatting that attackers use in web requests in an effort to bypass AWS WAF. If you specify a transformation, AWS WAF performs the transformation on fieldToMatch before inspecting a request for a match. e.g., CMD_LINE, HTML_ENTITY_DECODE or none. See docs for all supported values. Note: if you choose body as type, you must choose none because CloudFront forwards only the first 8192 bytes for inspection.

fieldToMatch

Arguments

  • data - (Optional) When type is header, enter the name of the header that you want to search, e.g., userAgent or referer. If type is any other value, omit this field.
  • type - (Required) The part of the web request that you want AWS WAF to search for a specified string. e.g., header, method or body. See docs for all supported values.

Attributes Reference

In addition to all arguments above, the following attributes are exported:

  • id - The ID of the WAF Size Constraint Set.
  • arn - Amazon Resource Name (ARN)

Import

AWS WAF Size Constraint Set can be imported using their ID, e.g.,

$ terraform import aws_waf_size_constraint_set.example a1b2c3d4-d5f6-7777-8888-9999aaaabbbbcccc
